Reply to comment by georgeBarkley12 in FDA wants to simplify the use and updating of Covid-19 vaccines by joshemerson

Right now it's more about which variant the vaccine protects against & not how long your immunity lasts.

Because we still have a very high infection rate, partly due to poor vaccination rates, we'll likely continue to see new variants outrun the time the vaccine remains effective.

That said, even a vaccine that doesn't specifically protect against the current variant will provide meaningful protection from a severe case (hospitalization, death, etc)

Their is no average as to how long protection is suppose to last?

It gets kinda complicated - mostly around what we consider “effective”. Does that mean prevents infection entirely, or does that mean prevents hospitalization, etc.

Here’s a good resource:

At the end of the day, if the CDC says you’re eligible for a booster then the booster offers significant advantages in terms of current protection.

Right now new variants are posing more of a risk than our immune systems “forgetting” about your last shot. Thankfully, vaccine manufacturers are releasing targeted vaccines for these variants which is what you’ll be vaccinated with if you get a booster.

Thank for this info, I’d also be curious as to what % of people are up to date on their boosters
